I have exactly the same problem, and I've read about many others with the same problems so I think's it's strange that this hasn't been resolved yet. "SID not found in PAT" on Canal+Sport HD, Canal+ FILM HD & TV2Sport HD1 & 2. Tried 2 other tuners and the channels work there with no problems, so this is a Dreambox problem.

It would be nice to know if it's a software problem or hardware.
